' V INsncT-ExTEnMINAToR.

To all whom it may concern: 1 Be it known that I, JOHN BIGGs, a citizen of the United States, residing at Kimball, in the county of Kimball and State of Nebraska, have invented a new and useful Insect-Exterminator, of which the following is a specification.

The invention relates to improvements in insect exterminators.

The object of the present inventionis to improve the construction of insect exterminators and to provide a simple, efiicient, and

comparatively inexpensive device designed for use in orchards, vineyards, and various other places for destroying white flies and various other insects injurious to fruit trees, grape vines, and various other trees and plants. v I

A further object of the invention is to provide a device of this character equipped with a light for attracting such insects and with means for positively spraying with poisonous vapor the insects which are attracted by the light.

With these and other objects in view the invention consists in the construction and novel combination of parts hereinafter fully described, illustratedin the accompanying drawing, and pointed out'in the claims hereto appended, it being understood that various changes in the form, size, proportions and minor details of construction, within the scope of the claims, may be" resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings: Figure 1 is a side elevation of an insect exterminator constructed in accordance with this invention. Fig. 2 is a plan view of the same. Fig. 3 is a vertical sectional view through the upper portion of the device. Fig. 4 is a detail sectional view on the line 1-1 of Fig. 3, showing the spray openings of the coupling.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates a tank or reservoir, of cylindrical or any other preferred shape, designed to contain a poisonous liquid, and provided at the top with a filling orifice and having an upwardly projecting flange or tube 2 thereat, threaded for the reception of a removable closurecap 3, The

tank is also provided at its upper portion with a suitable valve 4, adapted to be connected with an ordinary air pump or compressor for introducing air under pressure into the tank or reservoir for forcing the liquid contents thereof outward through a vertical discharge pipe 5, constituting a post and connected with the bottom portion of the tank or reservoir by a horizontal arm or branch 6. The horizontal arm or branch 6 is equipped with a suitable controlling valve 7 and the vertical discharge pipe 5 supports a horizontally disposed spray ring 8 connected at spaced points with the pipe 5 by a plurality of upwardly diverging tubes 9, forming arms and supporting the spray tube or ring 8. The tubes 9 diverge from a short stem 16, which is secured to the upper end of the discharge pipe 5 by a coupling 17, provided with a plurality of discharge perforations 18 drilled through the upper portion of the coupling substantially at an The coupling, with its discharge perforations, coeperates with the spray tube in exterminating the insects by discharging the poisonous liquid upwardly and outwardly at points below the said spray tube.

The spray tube or ring 8, which is provided in its upper face with suitable perforations 10 for the discharge of the poisonous vapor, has mounted upon it a tripod 11, constituting a support having a superimposed cap 12 and a lamp 13. The tripod consists of rods or legs secured at their lower ends to the spray tube or ring and connected at their upper ends. The conical cap 12, which is constructed of sheet metal or other material, covers the upper portion of the tripod and forms a deflector or shield for throwing the light downwardly. The lamp 13 is suspended from the hook 14, located within the conical cap, and suitably secured to the tripod or support 11.

The tank and the rest of the apparatus may be made in various sizes to suit the requirements, and when the apparatus is in operation, the poisonous vapor 1s discharged upwardly from the spray tube or ring, and insects attracted by the light will be subjected to the action of the said vapor and destroyed. Any liquid accumulating on the apparatus and dripping from the discharge pipe or tube will be caught withm a pro ecting trough 15, formed by a detachable pan 91 IQQBPl EQlB consisting of a horlzontal bottom 19 and a yertical Wall 20 extending up- 7 Wardly from the bottom 19 at the periphery thereof and arranged in spacedrelation with and surrounding the tank or reservoir.v The, projecting portion or trough of the'receptacle is adapted to catch and save consider-f."

able of the'liquid discharged from the device. The valve 7 enables the dischargeiofl the spray to be controlled to suit the characte'r of the material employed and the kind of insectsto be destroyed. I p The jet openings of' the coupling 17 may be"employed for sprinkling or spraying W li'enJ-a profusion ofspray is desired,rthe'- coupling and the spray ringareemfnloyed, but When-it is desired to use only the spray ring, a-plaincoupling may be substituted for the coupling having the jet openings;

The tank, which is'adapted to be arranged upon the-ground, constitutes a-bas'e for sup: porting the insect exterminator in an up right position The insect exterminator,

wliich-is portable; is adapted to-be readily transferred'from one place to another, and the spray ring, which is of COIlSldBI'flbl'V V greater-diameter'than the lampsis adapted to throw' a curtain- 'of"- sprayupwardly around -the' same. v
